ating SlidingWindow-Sash, &c.; and I hereby declare the following to be a full, clear, and exact description of the lnvention, such as w1llenable others skilled in the art to which it-pertains to make and use the same.

This invention relates to improvements in mechanism for actuating a sliding windowsash, door, or gate.

This invention relates more especially to mechanism which comprises two correspond ing racks arranged at opposite side edges, re-

\ spectively, of a window-sash between the sash' andthe window-casing and instrumental in lifting the said sash and held to the sash by latches arranged within and supported from the stiles of the sash and movable out of engagement with the racks against the action of springs which act to retain the said latches in their normal and operative position.

Another Ob ect of this invention is to provide flexible racks which are capable of movement in, under, and longitudinally ofthe sill ofthe window.

Another object of this invention is toconvveniently and compactly arrange below the window-sill the mechanism employed in operating the sash-actuating racks of a window having an upper sash and a lower sash with the two sashes capable of movement independently of each other.

v With these objects inview and to the end of realizing other advantages hereinafter appearing this invention consists in certain fea-. tures of construction and combinations of parts hereinafter described, and pointed out in the claims.

1n the accompanying drawings, Figure 1 is.- a slde elevation of a window havlng an upper sash and a lower sash and mechanisms for operating the two sashes independently of each i other from below the sill of the window, and portions are broken away and in section in this figure to more clearly showthe construction. Fig. 2 is a side elevation in section of a portion of a window-sash lowered against the window-sill. Fig. 2 is illustrative of a rack and the engaging latch. Fig. 8 is a side elevation in section corresponding with Fig. 2, except that in Fig. 3 the said latch is shown in its inoperative position. Figs. 2 and 3 are drawn on a larger scale than Fig. 1. Fig. 4is a top plan, mostly in horizontal section, on lined 4, Fig. 1. Fig. 5 is a side elevation in section, showing a portion of one of the flexible racks, the pinion meshing with the said rack, and means for preventing displacement of the said rack from the pinion.

In the drawings, A designates the windowcasing, B the window-sill, and C and C the lower sash and upper sash of y the window,

which sashes are arranged to slide in different vertical planes, respectively, and independently of each other in the usual manner.

Each stilec of each window-sash is provided at its outer side edge with a mortise 10,which contains a metal plate D, arranged vertically and secured to the said stile, as shown very clearly in Fig. 2, which illustrates a portion of a window-sash. In other words, each side edge of each window-sash is provided with a mortise 10, which extends to and is open at the bottom of the sash. Each plate D (see Fig. 2) is provided within the mortise containing it with a bracket 12, to which a latch E is pivoted horizontally, as at F, and the extension of the mortise to the bottom of the sash containing itthat is, to the lower end of the stilein which the said mortise is formedaccommodates the extension of a rack Gr upwardly into thesaid stile. Each mortise 10 is engaged, therefore, by a rack Gr, which abuts at itsupper end against the lower end of the latch-plate 1), contained within the said mortise. It is obvious, therefore, that each window-sash is lifted by the racks of the said sash during the upward actuation of the said ,racks and lowers by. gravity during the dc- ..scentof the said racks.

, Each latch E extends a suitable distance beow-its pivotal bearing and is provided at its lower end with a projection e, engaging in the normal and operative position; of, the latch, as

shown in Fi 2 with a recessf formed in the latch-facing and toothed sideof the adjahole 13. The said shaft H of course does not extend to the outer side of the sash provided with the said latch, but extends to the inner side of the sash, and the hole 13 in the said shaft extends to and is open at the inner side of the said sash, as shown in Fig. 1, to accommodate the reception from the last-mentioned side of the sash of a key (not shown) employed in turning the shaft. Aspring I engages the said latch and is applied as required to cause it to act to retain the latch in the latters normal and operative position, and obviously a turning of the said shaft H will result in the disengagement of the recess h by the latch and bring the unrecessed circumferential surface of the shaft into engagement with the latch, and thereby swing the latch into its inoperative position, as shown'in Fig. 3, against the action of the spring I;

It is obvious that when both latches E of a window-sash are rendered inoperative the said sash is rendered free to be lifted from the racks of the said sash and removed from the window-casing upon the removal of the windowstops J (shown in Fig. 1) and applied to prevent displacement of the said sash from the other sash and removably attached to the Window-casing in the usual manner. It is obvious also that the two racks employed in lifting a sash are actuated simultaneously in the one or the other direction according as the said sash is to belifted orlowered, and the said racks, as shown in Figs. 1 and 4, have their teeth upon their opposing and latch-engaging sides and extend through and below the sill of the window into the interior chamber Z; of the case K, formed next below the said sill which forms the top of the said case. The chamber Z0 extends longitudinally of the window-sill. Obviously the window-sill is slotted, as at 14, wherever required to accommodate the location and operation of a rack G, as shown in Fig. 2.

Within the chamber it are arranged two parallel metal bars M, extending longitudinally of the said chamber and suitably spaced apart transversely of the said chamber. The bars M are connected together and braced apart at the ends by two cross-bars N, which snugly fit within and extend transversely of opposite ends, respectively, of the chamber Two parallel shafts L and Z, arranged horizontally and transversely of the case K a suitable distance apart longitudinally of the said case, have bearing in the bars M. The shafts L and Z extend each beyond the outer side of the front of the case K and are angular at the said side of the said case, as shown in Figs. 1 and 4, to receive a crank 0 for turning the shaft, which crank is shown applied to the shaft Z. Two corresponding gears P and p are mounted upon the shafts L and Z, respectively. The gear P is operatively connected with the shaft L by the well-known means of groove and feather, as at Q, (see Fig. 4,) and the gear 9 is loose upon the shaft Z. The gears P and 19 mesh with each other and when rotated turn in opposite directions, respectively. The gears P and p are operatively connected with the racks Gr, instrumental in the actuation of the lower sash in such amanner that upon applying the crank 0 to the shaft L and thereupon actuating the crank the said racks are actuated in the direction required to lift the said sash or to permit the said sash to lower by gravity, according as the said crank is turned in the one or the other direction.

Two parallel axles R and r are arranged horizontally and transversely of the said case K within opposite ends, respectively, of the said case. The axles R and rare parallel with the shafts L and Z. Two corresponding pinions S and s are loosely mounted upon the axles R and 7", respectively. One of the racks instrumental in the actuation of the lower sash meshes with the pinion S, and the other rack employed in the actuation of the said sash meshes with the pinion s. The pinion S is operatively connected with the gear P, preferably by means comprising a sprocket-wheel T, which is integral and arranged in line axially with the said pinion and operatively connected by an endless chain U with a sprocket-wheel W, integral and arranged in line axially with the said gear P. The pinion s is operatively connected with the gear p,preferably by means comprising a sprocket-wheel t, which is integral and arranged in line axially with the said pinion and operatively connected by an endless chain a with a sprocketwheel w, which is integral and arranged in line axially with the gear p. The arrangement of the parts and the relative size of the sprocket-wheels T, t, W, and w are such that the racks instrumental in the actuation of the lower sash are during their actuation moved simultaneously in unison and in the same direction.

The means employed in the actuation of the upper sash is substantially the same as the means employed in the actuation of the lower sash and already described and (see Fig. 4) comprises, therefore, the following: Two corresponding gears 20 and 30 are mounted upon the shafts L and Z, respectively. The gear 20 is operatively connected with the shaft Z by the well-known means of groove and feather, as at 21, and the gear 30 is loose upon the shaft L. The gears 20 and 30 mesh with each other and when rotated turn in opposite directions, respectively. The gears 20 and 30 are operatively connected with the racks G instrumental in the actuation of the upper sash in such a manner that upon actuating the crank 0 when applied to the shaft Z, as shown, the said racks are actuated in the direction required to lift the said sash or to permit" the said sash to lower by gravity, according as the said crank is turned in the one or the other direction. Two corresponding pinions 22 and 32 are loosely mounted upon the axles '1' and R, respectively. One of the racks G instrumental in the actuation of the upper sash meshes with the pinion 22, and the other rack G employed in the actuation of the said sash meshes with the pinion 32. The pinion 22 is operatively connected with the gear 20, preferably by means comprising a sprocket-wheel 23, which is integral and arranged in line axially with the said pinion and operatively connected by an endless chain 24 with a sprocket-wheel 25, integral and arranged in lineaxially' with the said gear 20. The pinion 32 is operatively connected with the gear 30, preferably by means comprising a sprocketwheel 33, which is integral and arranged in line axially with the said pinion and operatively connected by an endless chain 34 with a sprocket-wheel 35, which is integral and arranged in line axially with the gear 30. The

relative size of the sprocket-wheels 23, 33,

25, and 35 andthe arrangement of the parts are such that the racks instrumental in the actuation of the upper sash are during their actuation moved simultaneously in unison.

and in the same direction.

By the construction and arrangement of parts hereinbefore described it will be observed also that the mechanisms instrumental in the actuation of the racks provided for the window-sashes are contained compactly with-i in the case K.

The gear P of themechanism employed in the actuation of the lower sash is normally locked against rotation'jby an endwise-shift able bolt (0, which is arranged within andlon-j 'gitudinally of the interior chamber /r: of the case K and has bearing in cross-bars m, which connect together and brace apart the bars M.

The said boltis arranged to engage the space between two adjacent teeth of the gear P and is operatively connected bya link f with the the actuation of the upper sash is normally locked against rotation by an endwise-shiftable boltZ), which is arranged within and longitudinally of the interior chamber 71; of the case K and has bearing in cross-bars a, which connect together and brace apart the bars M. The said bolt is arranged to engage-the space between two adjacent teeth of the gear 1) and is operatively connected by a link (Z with the upright arm 17 of an" oscillating shaft y, which is arranged horizontally and parallel with the shaft Z and has bearing in the bars VI. The shaft 9 extends through the front of the case K and is provided at the outer side of the said front with a crank 18 for turning the shaft, and obviously the said bolt is rendered inoperative upon oscillating the shaft 2 in the direction and to the extent required and must be rendered inoperative preparatory to the actuation of the upper sash. A suitably-applied spring j acts to retain the bolt 6 in its operative position.

The lower portion of each rack of the mechanism employed in operating either windowsash is composed, preferably, of sections assembled endwise with adjacent rack-sections pivoted together, as at 7, horizontally and transversely of the rack at the toothed face of the rack, so as to render the rack flexible and capable of movement into a compartment 26 of a stationary sheath 27, which is arranged within the lower portion and longitudinally of the interior chamber k of the case K, which sheath is provided at the receiving end of the said compartment with a flaring or outwardlyenlarged mouth 28 to facilitate the entrance of the said rack into the said sheath, and the outer side wall of the said mouth is extended upwardly, as at 29, at and next to the outer side of the path of the said rack and slopes inwardly, as at 8, toward the bottom of the said compartment, and hence forms a guide for insuring a proper entrance of the said rack into the said sheath. Figs. 1 and 5 very clearly show the sheath 27 for receiving the racks of the mechanism employed in operating the lower window-sash, and the upward extensions 29 of the outer side walls of the mouths of the compartments of the said sheath form arms which extend longitudinally of the racks and are interposed between the racks and the inner sides of the cross-bars N, as shown in Fig. 4, and prevent displacement of the racks of the said mechanism out of mesh with the rack-engaging pinions. It will be observed, therefore, that by the flexibility of the racks their extension below the case K is avoided and that in the lower positions of the window-sashes they are compactly received within the said case.

By the construction hereinbefore described it is evident that the racks employed in the actuation of either sash are removablysuspended from the said sash through the medium of the latches of the sash, and it will lOQOb-i served that adjacent sections of each rack are provided at their adjacent ends with straight surfaces which, abut against each other when the said sections are in line.
